18. Initialising the WP-81
If the calibration settings of the
WP-81
exceed the allowable limits, the
unit may need to be initialised to factory default values. This action may
be required if the sensor is replaced.
To initialise the
WP-81
:
1. Switch the
WP-81
OFF.
2. Press
and HOLD
the
key while switching the
WP-81
back on.
3. The following messages should
be displayed…
Initialized
MUST ReCalibrate
then :
WP81s V6.0 S1234
Con TDS Sal pH
o
C
(The “s” after
WP-81
is shown when the RS232 serial port option is
fitted)
4. The meter then displays Conductivity, pH and Temperature. Note that
the decimal points have
been replaced with a “
“, to indicate that the
unit requires re-calibration.
Notes:
1. The TDS Factor is reset to 0.65 when the meter has been initialized.
2. When the
WP-81
is initialised, the manual k factor selection is re-set
to k=10. See section 16 if you wish to select a k=0.1 sensor.
19. Instrument firmware version number.
If you need to contact TPS for any further technical assistance, the
version number of your
WP-81
firmware may of benefit to us. The version
number is displayed by the
WP-81
at turn-on.
